So, I have been getting what I assume is staking rewards (well, potential) on the wallet.  It shows the type as 'Mined' with a reward around 0.00001 (or an increment similar).  Each time it ends up as a "?" with a status of "conflicted, broadcast through 3 nodes".

I'm guessing these are the results of keeping my wallet open and staking.  So far all 6 of these instances have become like this.
Is this common to have so many [lack of a better word] failed stakes?
